Episode 66: Field School Diaries

The Story of Human Hair

Why do humans have most of our hair on our heads, not our bodies? Why do we have so many varieties of hair color, thickness, and curliness? Dr. Tina Lasisi is a biological anthropologist whose work explores these evolutionary mysteries. In this episode, she shares her research intowhy humans have scalp hair as well as her insights on why curly hair is uniquely human.

The Musical Ape

Music is universal in all human cultures, but why? What gives us the ability to hear sound as music? Are we the only musical species–or was Darwin right when he said every animal with a backbone should be able to perceive, if not enjoy music? Professor Henkjan Honing is on a mission to find out.
